Iningi lonjiniyela be-elekthronikhi bekufanele ngabe balidayisele ibhodii-soldering iron, kanti ithini le-solder linobuthi?
1.Ingabe i-solder tin ene-soldering iron inobuthi?
Abanye abasebenzisi be-inthanethi benza izikhalo mayelana neqiniso lokuthi wasebenzisa i-solder tin unyaka wonke embonini ye-PCB.Wezwa eseqala ukungakhululeki, nesisu sesivuvukala kancane.Ingabe wushevu womthofu?
Eqinisweni, kubuye kuncike ekutheni i-solder wire esetshenziselwa ukugoqa nge-soldering iron kagesi ayinawo umthofu noma ayisebenzi, futhi umthofu wegazi udinga ukuhlolwa njalo.Uma ingeqi ezingeni, ngeke kube nankinga nhlobo.Ingabe i-solder tin inobuthi?
Ngokuvamile, uma ukuvikelwa kanye nokuthengwa kwempahla eluhlaza kwenziwa ngokuvumelana nezindinganiso zikazwelonke, i-solder tin ngeke ibangele umonakalo omkhulu.Manje kusetshenziswa imikhiqizo engenamthofu.
Umthofu uyinto enobuthi.Ukumuncwa ngokweqile komzimba womuntu kuzodala ubuthi bomthofu.Ukuthatha umthamo ophansi kungase kuthinte ukuhlakanipha komuntu, isimiso sezinzwa kanye nesistimu yokuzala.Ingxubevange kathayela nomthofu iyona solder esetshenziswa kakhulu.Ine-conductivity enhle yensimbi kanye nephuzu elincibilikayo eliphansi.Ngakho-ke, sekusetshenziswe ubuchwepheshe be-welding isikhathi eside.Ubuthi bayo ngokuyinhloko buvela kumthofu.Intuthu yomthofu ekhiqizwa ngamathini asodayo ingaholela kalula ebusheni bomthofu.
Umthofu wensimbi ungase ukhiqize izinhlanganisela zomthofu, zonke ezihlukaniswa njengezinto eziyingozi.Emzimbeni womuntu, umthofu uzothinta isimiso sezinzwa esimaphakathi nezinso.Ubuthi bemvelo bomthofu kwezinye izinto eziphilayo buqinisekisiwe ngokujwayelekile.Ukuhlushwa komthofu wegazi kufinyelele ku-10 μ G / dL noma ngaphezulu kuzokhiqiza imiphumela ebucayi ye-biochemical.Uma kuvezwa isikhathi eside, ukugcwala komthofu wegazi kuzodlula ama-60 ~ 70 μ G/dl kuzodala ubuthi bomthofu emtholampilo.
Umthofu kufanele ube nobuthi.Ingasaphathwa eye-solder tin inomthelela omncane emzimbeni.Ngisho nezinsimbi ezejwayelekile zizofakwa ubuthi uma ziziningi kakhulu.Lapho i-soldering tin, kuzoba nentuthu, equkethe into eyingozi emzimbeni.Uma usebenza, kungcono ukugqoka imaski, kodwa kusazoba nomthelela othile.Kunjalo, uma ungasebenzisa i-lead-free solder wire, izophepheka kakhulu kunalezo ezinomthofu.
2. Ingabe i-solder engenawo umthofu inobuthi?
Impahla esetshenziselwa ukuhlanganisa ithini ngensimbi yokuhlanganisa kagesi iyintambo ye-solder.Nakuba ingxenye yayo eyinhloko inguthayela, kodwa iqukethe nezinye izinsimbi.Ihlukaniswe kakhulu ibe umthofu kanye ne-lead-free (okungukuthi uhlobo lokuvikela imvelo).Ngokwethulwa kwezinga le-EU ROHS, izimboni zokushisela ze-PCB ziya ngokuya zikhetha ezinganawo umthofu futhi zivumelana nemvelo.Intambo ye-lead solder nayo iyashintshwa kancane kancane, engahambisani nemvelo futhi ayikwazi ukuthunyelwa ngaphandle.I-solder yamahhala enamathiselwe ngomthofu, izintambo ezingenamthofi nethayela elingenamthofu yimikhiqizo eyinhloko emakethe njengamanje.
Ukukubeka kalula: ithini elisetshenziswa ngokuvamile liwubuthi ngenxa yephuzu elincibilikayo eliphansi, eliqukethe u-60% womthofu kanye no-40% wethini.Iningi lamathini asodayo emakethe alinalutho futhi line-rosin, ngakho-ke igesi oyishilo ilinganiselwa ukuthi izoshintshashintsha uma i-rosin ethanini elihlanganisiwe incibilika ngesikhathi sokushisela.Igesi eshiswe yi-rosin nayo inobuthi obuncane.Le gesi inuka kabi.
Isici esiyinhloko esiyingozi se-soldering tin intuthu yomthofu.Ngisho nethayela elihlanganisiwe elingenawo umthofu liqukethe inani elithile lomthofu.Umkhawulo wentuthu yomthofu ku-gbz2-2002 uphansi kakhulu futhi unobuthi, ngakho udinga ukuvikelwa.Ngenxa yokulimala kwenqubo yokushisela emzimbeni womuntu kanye nemvelo, eYurophu, ukuvikelwa kwabasebenzi be-welding kanye nokuvikelwa kwemvelo kuye kwaphoqelelwa ngendlela yomthetho.Ukushisela ngaphandle kwezinyathelo zokuzivikela akuvunyelwe.Ngokwezinga le-ISO14000, kunezinhlinzeko ezicacile zokwelashwa nokuvikela ukungcola okukhiqizwa kuzixhumanisi zokukhiqiza.
Ithini liqukethe umthofu.Esikhathini esidlule, kwakunomthofu ocingweni lwe-solder.I-Solder ihlukaniswa njengeposi eliyingozi emsebenzini (kukhathalogi kazwelonke yezifo zasemsebenzini);Manje amabhizinisi ethu ajwayelekile asebenzisa intambo ye-solder engenamthofu.Ingxenye eyinhloko ithini, futhi isikhungo Sokulawulwa Kwezifo kanye nokuvimbela silinganisa i-tin dioxide;Alikho kukhathalogi yezifo ze-National Occupational Occupational.
Ngokuvamile, intuthu yomthofu enqubweni engenamthofu ngeke yeqe izinga, kodwa kunezinye izingozi ethini lokusoda.Isibonelo, i-soldering flux (izinto ze-rosin) inezingozi ezithile, okufanele zibonwe ngokuvumelana nesimo esithile.Abasebenzi ngokuvamile bangabheka ukuhlonzwa kanye nesigaba samathini asabalalisiwe, ukuze abhalwe kahle futhi adinge ukuthi inkampani yenze ukulungisa (bangakwazi ukunikeza imibono kunyunyana yabasebenzi yangaphakathi efektri).Uma ithini liqukethe umthofu, kufanele libe yingozi empilweni yakho.Ngokuhamba kwesikhathi, zinqwabelana emzimbeni futhi zidale umonakalo omkhulu kumasosha omzimba wesimiso sezinzwa.
I-lead free solder wire ihambisana nemvelo, kodwa i-solder engenawo umthofu iphinde ibe yingozi emzimbeni womuntu.Okuqukethwe kokuhola okuphansi kwentambo ye-solder engenamthofu akunawo umthofi.Uma kuqhathaniswa nentambo ye-solder equkethe umthofu, intambo ye-solder engenamthofu inokungcoliswa okuncane kwemvelo nomzimba womuntu kunocingo lwe-solder olunomthofu.Igesi elakhiwe ngesikhathii-solderinginobuthi, okuhlanganisa uwoyela we-rosin, i-zinc chloride namanye amagesi.
I-3, Ungayivimbela kanjani insimbi kagesi e-soldering kanye ne-solder wire ekubeni nobuthi
Okokuqala, amafekthri e-PCB kufanele asebenzise i-RoHS tin wire lapho e-soldering izingxenye nge-electric soldering iron, futhi enze umsebenzi omuhle wokuvimbela: isibonelo, gqoka amagilavu, imaski noma imaski yegesi, unake umoya omncane emsebenzini, ube nokukhipha okuhle. uhlelo, unake ukuhlanza ngemva komsebenzi, futhi uphuze ubisi kungavimbela ubuthi bomthofu ku-solder tin.
1. Ukuphumula isikhathi esithile: ngokuvamile, kufanele uphumule cishe imizuzu engu-15 ihora ukuze unciphise ukukhathala, ngoba ukumelana kubi kakhulu uma ukhathele.
2. Gwema ugwayi kancane futhi uphuze amanzi amaningi, angaqeda izinto eziningi eziyingozi ezimuncwa emini.
3. Phuza isobho likabhontshisi noma amanzi oju ngaphambi kokulala, okunganciphisa umlilo futhi kukusize uzizwe ukhululekile, futhi ubhontshisi we-mung noju kungaqeda inani elikhulu lomthofu kanye nemisebe.
4. Gwema imisebe futhi uzame ukugwema ukulinda omakhalekhukhwini.
5. Ungakwazi ukukhanyisa insimbi ye-soldering bese uzama ukusebenzisa ikhanda lokushisela le-PPD.Ngale ndlela, lapho izinga lokushisa lifinyelelwa, ungasebenzisa amafutha amancane okushisela kanye ne-rosin ukuze unciphise ukulimala emzimbeni wakho,
6. Uma amafutha asodayo kanye nethini kushunqa, zama ukuxubha isibhakabhaka ngekhanda lakho eceleni, bese uzama ukubamba umoya wakho lapho uxubha amanzi.
7. Sebenzisa amanzi e-Tianna amancane, sebenzisa utshwala obuningi, futhi uxube okwengeziwe ngotshwala isikhashana.Umphumela ucishe ufane.
8. Geza izandla zakho.
9. Geza ngaphambi kokulala.Zama ukulala futhi uvuke ekuseni ukuze uqinisekise ukulala ngokwanele.Uma nje ulala kahle, ukungcola kungakhishwa ngomzimba wakho.
10. Sebenza ngezifihla-buso.
